About Staurogyne repens
Staurogyne repens · also called creeping Staurogyne, low-growing Staurogyne · tropical
Staurogyne repens is a hardy carpeting aquarium plant from Brazilian river margins, grown fully submerged in freshwater tanks. It forms a dense, low bushy foreground of bright green oval leaves on creeping stems. Easy to keep, it tolerates a wide range but stays compact and carpets best under strong light with added CO2.
Growth habit: Low, creeping and bushy; sends out lateral shoots that root into the substrate to form a spreading foreground carpet.
Watch for — Algae on leaves: Slow growth from low CO2 or excess nutrients lets algae coat the broad leaves; balance light, CO2 and dosing and increase water flow.
What fertiliser staurogyne repens actually wants — and why
Staurogyne repens is an easy, light foliage feeder — a half-strength balanced liquid feed through the growing months keeps it green without forcing weak, sappy growth.
A balanced general houseplant feed (roughly even N-P-K) is exactly right — it is grown for foliage, so steady, moderate nitrogen for healthy leaves is the goal, not a bloom or root formula.
For the language behind the three numbers on the bottle — what nitrogen, phosphorus and potassium each do — see the NPK ratio explained entry. The short version for staurogyne repens: match the feed to the job the plant is doing right now, not to a generic “plant food” on the shelf.
How often to feed staurogyne repens, and which months
Feeding only earns its keep while the plant is in active growth and can use the nutrients — pour feed into a dormant or low-light plant and it simply builds up as root-burning salt. For staurogyne repens:
Benefits from a complete liquid aquarium fertiliser plus root tabs; responds strongly to injected CO2, which boosts density and color. In low-tech tanks it grows slower but steadily with regular dosing. Treat that as sparingly through the growing season between spring through early autumn (roughly March to September); ease off in autumn and stop entirely in the low light of winter.
The dormant-season rule matters more than the exact interval: skip feeding entirely when staurogyne repens is resting. For the wider context on indoor feeding rhythms across the seasons, the houseplant fertiliser schedule walks through the year month by month.
What strength to mix for staurogyne repens
Half strength is the safe default for staurogyne repens — houseplant feeds are formulated strong, and the diluted dose is gentler on the roots while still ample for foliage.
Feeding always goes onto already-damp soil, never dry roots — water staurogyne repens first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the staurogyne repens watering schedule.
Signs you are over-feeding staurogyne repens
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for staurogyne repens:
- Brown, crispy leaf tips and edges with no sign of underwatering.
- A white, crusty salt deposit on the soil surface or pot rim.
- Weak, pale, stretched new growth that flops.
- Lower leaves yellow and drop while the soil is correctly watered.
Signs you are under-feeding staurogyne repens
- Uniformly pale or yellow-green leaves, oldest first.
- Noticeably small new leaves and stalled growth in good light and season.
- A generally tired, lacklustre look despite correct watering and light.

Flushing and leaching the salts
Flush the pot of staurogyne repens with plain water until it runs freely from the base every couple of months in the feeding season — it washes out the fertiliser salts that cause brown tips.
Organic vs synthetic feeds for staurogyne repens
Organic options
A diluted seaweed or worm-casting feed, or fish emulsion if you can tolerate the smell indoors. UK: Westland or Baby Bio Organic, dilute seaweed; US: Espoma Indoor! or Neptune's Harvest fish & seaweed. Slow, gentle and hard to overdo.
Synthetic / liquid feeds
A general-purpose houseplant liquid at half strength — UK: Baby Bio, Westland Houseplant Feed or Phostrogen; US: Miracle-Gro Indoor Plant Food or Schultz. Convenient and fast-acting; the only risk is overdoing it.
Brand names are examples, not endorsements, and UK and US ranges differ — check the label’s own NPK and dilution rate, since formulations change.

What does over-feeding staurogyne repens look like?
Brown, crispy leaf tips and edges with no sign of underwatering. A white, crusty salt deposit on the soil surface or pot rim. Weak, pale, stretched new growth that flops. Lower leaves yellow and drop while the soil is correctly watered. Feeding staurogyne repens year-round on a fixed schedule, including dark winter months, is the most common mistake — it cannot use the nutrients in low light and the surplus simply burns the roots and crusts the soil.
Should I flush the soil of staurogyne repens?
Flush the pot of staurogyne repens with plain water until it runs freely from the base every couple of months in the feeding season — it washes out the fertiliser salts that cause brown tips.
